Thanks for this information. I bought my used and only a key fob. Worked great for couple months then started giving out of range. Now I have to press the button to get it to light up. dealer updated and check all out, it does not see the fob with it turned on. But if i continue to press the button with green light it will eventuly start up. They ordered new fob and keys but 4-6 weeks. grrr. Why not generic key fob and just swap the key? FYI I also have scrambler 1200 with key fob never had an issue in 3 years. are they not all using a common system?
